The 3.99% rate, one of the lowest in the state, which matches those offered by banks, is aimed at demonstrating both pricing benefits from the merger of the former NuUnion CU of Lansing and Detroit Edison CU as well as serving as an attention grabber in the market, said the CU.

"It's still a little early to say what kind of volume we're getting on the loans since we started April 1 and it has been a slow time on autos," said James Costello, senior vice president. The rate became effective at the start of the month when the NuUnion/Detroit Edison marriage became official.

Danielle Brehmer, vice president-marketing, said the lower fees and rates on Lake Trust products are designed to show the membership "that we appreciate them and their loyalty."

Lake Trust, with 22 statewide branches and fourth largest in the state, began its celebration last week with a grand opening party marked by a three-foot tower made up of 100 cupcakes "representing the more than 100 combined years of service to members."
